SPECIFIGATION for-xning part of Letters Patent No. 247,568, datedSeptember 27, 1881.

Application filed July 30, 1879.

To all whom it may concern:

Be it known that I, HENRY LETZEISER, of the city, county, and State ofNew York, have invented certain new and useful Improvements inInterchangeable Inking-Beds for Printing- Presses, of which the followingis a Specification.

In theaccompanying drawings, Figure 1 represents a side view of aprinting-press with my improved chromatic attachment. Fig. 2 is a frontelevation of the same; and Fig. 3, a detail vertical transverse sectionof the chromaticinking-table on lineman, Fig. 1. Fig. 4 is a perspectiveview of my improved chromatic attachment without the inking strips. Fig.5 is a vertical section of the chromatic attachment. and itsinking-strips, and a section of the supporting eye-standard of theprinting-press.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish for printin g-presses animproved chromatic attachment, which is so constructed as to be readilysubstituted in place of the common inkingdisks, and adapted to printtransversely across the sheet in different colors and by one impression.

The nature of my invention consists in the combination,in aprinting-press provided with an eye-post and side checks, of a table orframe having a bed-plate, raised side cheeks, rear extension-armsthereof, a contracted extension of the table forward of the said cheeks,and a centrally-arranged stud, all combined and arranged in such manneras to constitute a complete chromatic table adapted for theinking-strips, and also interchangeable with the common inking-table toadapt the press for plain or chromatic printing.

Referring to the drawings, A represents a printing-press of any desiredconstruction, to the eye-standard Z on the frame of which is attached acompound chromatic inking-table, B. When the table B is adjusted on thepress in place of the common inking-table, the stud p of the table beinginserted through the eye of standard Z, the front contracted eXtension,Bof the table B fits snugly between the vertical cheeks A A of thepress-frame and the shoulders or front ends of the side cheeks, B, ofthe table abut against the upper ends of the cheeks A A. My chromatictable attachment is thus constructed with reference to the press shownin the drawings, so that the table is held rigid when properly appliedto the press, and while this is the case it will be seen that the pressdoes not require any change whatever in order to adapt my table to it.

The curved arms B constitute another important feature of my chromatictable attachment, which arms are extensions of the frame or rails B, andare intended to afford supports for the wheels b b of thedistributing-roller D when this roller is moved back of the inkingstrips0, as indicated in Fig. 5, to allow the inking-roller to be moved oversaid strips.

To the frame B of the table B are looked a series of longitudinal inkingstrips, 0, a certain complement of which has to be provided for eachpress, according to the range of the work to be accomplished thereon.These inking-strips U are of different widths, and correspond to thewidths of the different lines of type. They are spaced or leaded in sucha manner as to correspond to the transverse-lines of type in the form,each line having a separate inking-strip of corresponding width. Theinking-strips may be locked to the frame of the table B by transversewedge-shaped keys at a, or in other suitable manner, after the leads andend fillersare putin. Theink is supplied either by anadjustably-partitioned fountain or, in small hand-presses, by a stiffbrush or other suitable means, the different inki n g-strips receivingthe proper colors selected for the different lines of type.

The inkdistributin g roller or set of rollers D is connected to arms Dof the oscillating frame E, which carries the inking roller or rollersE. The ink-distributing as well as the ink-transferring rollers areretained by means of spiral springs in contact with the ink-distributingstrips and with the form, the ink-distributing rollers being guidedduring the backward motion on arc-shaped extension-arms B of the frameof the inking-table.

The chromatic inking attachment is so constructed as to be readilyattached to the supporting-frame of the press in place of the commoninking devices whenever it is desired to do chromatic printing. Theattachmentis not expensive, and extends the range of the printingoperations both in power or hand presses and for job and amateurprinting.

I am aware that chromatic attachments formed of interchan geableinking-strips or type game well known, and have been used hereto- Having thusdescribed myinvention, I claim 5 as new and desire to secure by LettersPatent- The combination, in a printing-press which is provided with aneye-post and side cheeks, of the detachable chromatic table, consistingof the following elements: a bed for the ink- 10 ing-strips, contractedat B a stud on the bottom of this bed, side cheeks or frame, B, and
